Detailed Solution

Concept- The given reaction is an example of hydrolysis. When both the reactant and product sides of an equation have the same quantity of each element, the equation is balanced. To accurately depict the rule of conservation of matter, equations must be balanced. A chemical equation needs to be balanced so that the total mass on the reactant side and the total mass on the product side are equal. Any chemical reaction in which a water molecule breaks one or more chemical bonds is known as hydrolysis.
Calcium hydroxide is created when calcium oxide and water interact. When water is added to dry portland cement to create concrete, a reaction takes place, and heat evolution of energy as heat is obvious since the material warms up. Following is the reaction that occurs:
